Answer 1

1. Doctor orders Amoxil for a child that weights 65lbs= 29.54 kg

The safe dosage range for this medication is 50 mg/kg/day every 8 hours.

The safe dose for this child per dose will be=50 X 29.54= 1,477.27 mg/day every 8 hours.

2. Doctor orders Zofran= 2 mg

Child weight= 15kg

The safe dosage range for this drug = 0.5 mg/kg.

Hence in case of this child the safe dose range will be = 0.5 X15=7.5 mg

The Doctor's order is safe as the ordered dose i.e. 2mg of Zofran is below the safe dose level i.e. 7.5 mg as per the child weight is considered in the dose determination.

3. Doctor’s order of Zithromax= 150 mg

Child weight= 82 Ib= 37.27 kg.

The safe dosage range for this medication is 10-12 mg/kg/day.

1. The maximum safe daily dose for this patient will be =37.27 X10 to 37.27 X12

                                                                                     = 372.7 mg - 447.24 mg

b) The doctor's order is safe as 150 mg dose is below the safe range i.e. 372.7 mg - 447.24 mg
